To all whom it may concern.-

Be it known that l, H WARD DUDLEY, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have in vented certain new and useful Improvements in Dyei1 1g-Maehines, of which the following is a specification.

My invention relates to dyeing. machines and refers particularly to those machines in which textile fibers are dyed under compression, the dye liquor being forced through the compressed mass. I I The dyeing of fibers under these conditionspresents many difliculties, as it is es sential that all parts of the fiber mass be treated absolutely equally by the dye liquor, as otherwise uneven results will be obtained. v i

This equal treatment is dependent upon a number of conditions ;,The fiber must be uniformly and properly compressed, the liquor must be at a uniform pressure throughout the fiber mass, the formation of channels or passages within the fiber mass must be avoided, the dye liquor must be of such dilution as to prevent precipitation upon the fiber, the temperature of the liquor must be properly retained and means must be employed for determining the condition of the dyed fibers without interrupting the dyeing oper ation, opening the dyein chamber or, dis turbing or sampling the iiberbeing dyed.

The device of my invention accomplishes all of the above results in a mannereconomt cal in construction and cheap, simple, accurate and positive in operation and possesses other advantages which will be evident upon a consideration of my specification, drawings and claims.

in the dyeing of fibers under these conditions, it is essential that as much as possible of the lower surface or layer of the fiber mass be subjected to the liquid, and T have found that this can be accomplished to a maximum degree by allowing the fiber mass to rest upon a series of upwardly extended hollow cones, having perforated sides, particularly effective results. being attained when these openings are vertically extended openings ofv a curved character. This formation allows practically the entire lower surface of the fiber mass to be treated equally y the li uid? A similar plate, having the hollow perforated cones downwardly extended when placed above the fiber mass, causes uniform pressure and distribution of the liquid through the compressed fiber mass.

In order to obtain a uniformly distributed pressure against the faces of the foraminous plates, I introduce an approximately semispherical member through which the liquid s forced, said liquid supply member having within it a series of solid curved members so shaped and arranged as to impinge the liquid equally and uniformly upen the faces of the plates.

In order to judge of the condition of the process, I have a small dyeing device exactly similar and proportionate to the larger device and so. constructed that fiber inserted therein will receive exactly the same treatment as that in the larger device, the same proportionate amount of the same liquor passing through both under the same pressure and temperature, so that in order to determine theconditi on of the dyeing, the operation in the large device need not be even interrupted, the large device need not be opened, and it will not be necessary to disturb the fiber contained therein.

In the drawings, illustrating modified forms of the device of my invention, similar parts are designated by similar numerals.

Fig. 7 is a broken cross-section of a portion of a modified form of the distributing members below the foraminous plate.

The device of my invention illustrated in the drawings, comprises a cylindrical dyeing receptacle having the side Wall 10, affixed to the liquid distributing chamber 11 by means of the screw-bolts 12, 12. The distributing chamber 11 is fixed to the delivery chamber 13 of the pump 14; by means of the serev ee s 15, 15-! the ret rin h mber of the pump 14 is connected with the pipe 16, which in turn is connected with the pipe 17 having the valve 18, the pipe 17 being tank 23. The upper portion of the dyeing receptacle is connected with an over-flow pipe 24, which enters the upper portion of the reserve tank 23. The side wall 10 of the dyeing receptacle has an annular oifset 25, upon which rests the foraminous plate 26. The upper portion of the side wall 10 is extended outwardly into the annular flange 27. A removable annular angular member 28 is capable of insertion within the dyeing receptacle and is movable therein by means of the screwrbolts 29, 29, passing through the member 28 and threaded within the member 27.. The member 28 is capable of surface engagement with the upwardly extended annular members 30 of the foraminous plate 31', openings 32, 33 allowing of the passage of a liquid therethrough for purposes to be described later. A conduit 34, opening below the foraminous plate 26 is connected with the pipe 35 having the valve 36. The pipe 35 above the valve 36 is connected to the testing device 37 by means of the coupling 38, the testing device 37 having the annular oflset39, in order to make a tight joint. The upper portion of the testing device 37 is similarly joined to the member 27 by means of the coupling 40, and is connected to the conduit 41, which enters the receptacle through the opening 32 into the receptacle above the foraminous plate 31. The distributing member 11 contains a series of parallel plates 42, 42, which are curved tocorrespond with the sides of the distributing chamber 11 and which converge downwardly to an approximately sharp edge, the object of the shape of the member llrand the plates 42, 42 being to distribute the liquid pressure uniformly and; evenly. A pipe 43 having the valve 44 is connected with the delivery chamber 13. A perforated steam pipe 45 is situated below the foraminous plate 26.

The forai'ninous plates 26 and 31 are similar in construction and comprise a series of bers 42, 42, curve downwvardly and inwardly to somewhat conform with the shape of the member 11.

The operation of the device is as fol.- lows:

The annular member 28 and the for-aminous plate 31 are removed, the fiber 100 is placed within the receptacle and upon the foraminous plate 26. The plate 31 and the member 28 introduced and the plate 31 forced downwardly upon the fiber 100 by means of the screw-bolts 29, 29 until the de sired pressure is obtained. All of the valves are closed with the exception of valves 18 and 36 and the pump 14 started. Liquid flows from the dissolving tank (not shown) through the pipe 17, the pipe 16, the pump 14, the distributing chamber 11, the plate 26, the fiber 100, the plate 31, the opening 33, and the pipe 24 into the reserve tank 23. At the same time the liquid is forced through the conduit 34, the pipe 35, the fiber within the testing device 37, the conduit 4]. and the opening VVheu sufiicient liquid has been pumped into the device, the valve 18 is closed and valve 22 is opened and the liquid is thus given a continuous circulation through the dyeing device and the reserve tank 23. From time to time the valve 36 is closed, the testing device- 37 is removed and the condition of the dyeing observed and the testing device 37 replaced.

When the dyeing operation is finished, valve 22 is closed, the pump 14 stopped and valve 44 opened thus drawing the liquid from the device.

The dyed goods are washed by closing valve 44, opening valve 20, starting the pump 14, and connecting pipe 24 with a drain. hen the goods are sutliciently washed, valve 20 is closed, the pump 14 stopped and the valve 44 opened thus draining the wash water from the device.

Ido not limit myself to the particular size, shape, number or :n'rangement of parts as illustrated and described, all of which may be varied without going beyond the scope of my invention as described and claimed.
